Saving Data on Android

initializeURIMathching
. In this function, add each URI 
that this content provider can match with. This provider will accommodate a URI 
to retrieve a single record with an id hence the 
#
, a URI to get all the records, and 
a URI to get a count of the number of records. Each URI includes the authority, 
the content path, any arguments represented by special characters, and a unique 
code.
3. Declare some constants that represent the numeric code for the URI. The 
contract class gives descriptive names to the corresponding values these codes 
will match with. These codes are unique and chosen by the developer.
The next step is to start implementing the stub methods one by one. The template 
doesn't always put them in the most logical order by default. You can reorder them if 
you like.
